Real-time database is an important database service system for weather forecasting and relevant operational application development.It also plays a key role as a data support environment in the weather information service process,which is foundation to ensure timely and efficient operation from the observed forecast to the end user.In this paper,a framework and some developing principles of monitoring system for real-time meteorological database are proposed.Additionally,it analyzes the advantages and high scalability of this architecture.Based on service monitoring and control(SMC) framework,a service-based meteorological real-time database monitoring application named RDBCat has been developed and deployed in National Meteorological Information Centre(NMIC).In response to the requirements for function and performance in real-time database service,the display of many real-time operating statuses is provided,such as the storage situation,the key process run on commercial relational database system,the fault information,the data pre-process,the system resources,data quality,and the details data storage of the every province.At present,RDBCat has been stable operation for daily service support up to now.In particular,it supports good service in the Olympics,the Asian Games and other major events.
